Overview
All of your TMA experiments will have the
following general outline. In some cases, not all
of these steps will be performed.
• Selecting and calibrating the appropriate
probe type
• Entering experiment information through
the TA controller (sample and instrument
information)
• Creating and loading the thermal method on
the controller
• Attaching and setting up external
accessories as required ( e.g., purge gas, air
cool, gas switching accessory)
• Zeroing the probe
• Preparing and loading the sample
• Adjusting the thermocouple position
• Measuring sample length
• Adding coolant to the furnace reservoir for
subambient operation.
• Starting the experiment.
To obtain accurate results, follow the procedures
carefully and check calibration periodically
(once a month). Consult the online documenta-
tion for details on calibrating the TMA.
